# Miles Per Hour to Mach Converter

> Miles Per Hour to Mach Converter is a paid API for AI agents from agent402.tools, paid per call via x402, $0.001/call, status down (last checked 2026-09-15).

Converts a speed value from miles per hour (mph) to Mach number via a simple GET request.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability miles-per-hour-to-mach-converter-5dec0ba6
```

Example prompt: Convert 760 miles per hour to Mach number for me.

## When to prefer this

Use this endpoint when you need a quick, single-value conversion from mph to Mach and want a lightweight, pay-per-call API without managing a full unit-conversion library. Ideal for aviation, engineering, or physics contexts where Mach number is the required output unit.

## Known failure modes

- Missing or non-numeric value parameter returns an error
- Negative values may be rejected or produce unexpected results
- Service unavailable if payment (x402) is not properly handled

## How this service works

Convert miles per hour to mach (speed). Pass ?value=N.

## Output

Returns the Mach equivalent of the given miles-per-hour value — a dimensionless number representing the ratio of the input speed to the speed of sound (e.g., Mach 1.0 ≈ 767 mph at sea level).
